To all whomit may concern;

Be ,it lcncwnthatl, JOHN H. J. Haines, a citizen of the United States,residing at the city' of New York, in the borough of Manhattan and State:of New York, have invented certain new and useful Improvements inPhonographs, o i' which the follow'- ing is a full, clear, and exactdescription, l

rlhis .invention :relates to phonographs and other styles of talkingmachines in which the record is traced in atabletl in the :t'orm of agroove varying in depth in accordance with the vibrations of the soundsof. talking machine it has been customary to employ one 'devlc'e'forrecording sounds and another for reproducing them. These devices eachcomprise essentially a. diaphragm mounted in a. sound box and carryingAa stylusllwhich engages the surface of vthe; record tablet. In= therecorder the stylus is caused to cutagrcme of vary-ing depth in therecording surface, while in the repro,-

' ducer the stylus, which is of slightly differentrconstruction, isadapted to traverse-the groove formed by the recorder and to transferl'the undulations of the groove successively to the diaphragm.Anfessential difference in these two devices is that. the reproducerwhen-in action rests more heavily against the record surface thandoesthe recorder. The reason forthis is that in recording, theinstrumentshould be in a nearly floating condition with its styluslocated so as to. just cut the record surface land its movements not beinterfered with by the inertia of theirame in which the di'ardiraglm`words 1t mustl be `as` is supported. In other sensitiw-'e as possible tosound vibration. In the reproducer, on the contrary, `=the -device wouldnot act properly if it were in afloating condition because theirregularities or" the record groove which are driven against thestylus' by `the rotating Atablet would cause stutter and give imperfectreproduction. Therefore. in-A the reproducer it is the common practiceto add weight to the frame on which the diaphragm a nd stylus aresupported, s'o as to hold the stylus to its work in V,the groove. Hence,

' aside from the difference in the form of the 'stylus points, theessential difference between a' recorder and la reproducer is that t thelatter is heavier than the former.

'Heretofore and prior to my. invention it has been customary, where thetalking machine is intended Jfor both recording and reproducing, toprovide the machine with two separate and distinct devices, one to beused for the recording, and this to be removed and replaced by theother, for reproducing.

lt is the object of my invention to provide in one and the sameinstrument, both the recording and reproducing devices, and in so doingto utilize a single head which comprises a diaphragm1 sound box andframe. ll accomplish this by providing a weight or spring so arrangedthat when the head is in` a position to record, it will be independentot and uninfluenced by the weight or spring, but when the head is throwninto a position to reproduce, the weight-'or spring is automaticallybrought to bear upon it so as to afford the necessary additionalpressure against the record surface required in the reproducingoperation.

` To be` more specific, my invention consists lof arecorder-reproducercomprehending a single diaphragm having attachedthereto a recording and a reproducing stylus, means for bringing intoactive position either one of the styluses atwill, and means whereby aweight or the force of a spring will be added to or removed from theinstrument accordingly as the reproducingor the. recording stylusesarethrown into action. My invention thus very much simplifies the operationof talking machines as well as reduces their l cost and the timeordinarily required to yshift from the recording to the reproducingdevice .is .almost entirely saved.

My invention will be now described with reference to the accompanyingdrawings, in

which:

Figure 1 is a 'plan of -a portion of the .trame ot a phonograph, showingmy .oom- ,bined recorder and reproducer 1n operative position thereon'and utilizing a weight instead of a spring; Fig. 2 is an end elevationof the same machine with the recorder-reproducer adjusted for the,recording operationj` Fig. 3 is a view similar to- Fig 2 with therecorder-reproducer adjusted for the reproducing operation; Fig. i is avieuT showing the device in condition for recording, but with a springsubstituted forthe weight; Fig. `."5 illustrates/a'modification in the.construction of Athe weight in connection with a modification of themanner of shitting the stvluspoints; Fig. 6 is a section on line X-X ofFigQ; and Fig.7 is a section on line Y-rY'jofFig. 5. 1

Referring to the drawings by numerals, 1 indicates the frame of thephonograph in which is mounted the tapering cylinder 2 which supportsthe record tablet in the form of a cylinder and indicated by 3.

1 is a rod along which the carriage 5 travels.

The recorder-reproducer consists of a sound box or frame 7 in whichismounted the diaphragm, and a Atubular arm 8 to which the sound box ispivoted at 9 and which communicates with the interior chamber thereofabove the diaphragm. The arm 8 is connected by means of a universaljoint 10 with the carriagel 5 and the latter is providedwith a nipple 11to receive the end of a flexible tube and through which a pas sage leadsinto the arm 8, thus forming a. continuous sound passage from the upperside of the diaphragm to and through the flexible tube, the outer end ofwhich is to be attached as usual to the mouth piece or horn.

At or near the center of the diaphragm are fixed two stylus points 12and 13, the

- 9 serving as a stop.

Ament with the record tablet.

15 is a lever pivoted. to the end of arm 8 and having lan eccentric lug16 which is adapted, in oneA position of thelever, to bear against andtiltl the sound box 7 into Ian oblique position, as shown in Fig. 3,while when the lever is thrown upward into its other position as inFig.2, the sound box is permitted to return to a horizontal position underthe action of and be held by, the

spring 1&1. When the sound box is in the horizontal position, therecording stylus 12 is in position to engage the record surface of thetablet 3, as seen in Fig. 2, and lwhen the sound box is in the obliqueposition, the stylus 12 is thrown out of contact with the record surfaceand the stylus 13 is thrown into'op'erative position therewith.

Pivotally attached to the carriage 5 at the point 16 is a bracket 17provided with a lug 18 adapted to be engaged by another lug 19 which ismanipulated by a hand lever 20 to raise and lowerlthe instrument. Theinstrument for the purpose, is provided with a tongue 21 which bearsagainst al shoulder on the bracket 17 as shown, so thatywhen the bracketis swung upward, the instrument is raised and can be moved along the rod4 to any desired position and when the bracket is lowered, it will dropinto engage- Thfis device for raising and lowering the instrument is anordinary one and forms no part of my 6.5 present invention. Preferablyattached to this bracket 17, however, by means of a pivot 21 is aweighted lever 22, being a bifurcated plate embracing the opposite sidesof the tubulai` arm 8. This lever has a projection 23 carrying a setscrew 24 which may be adjusted to determine the elevation of the leverwhen supported at its lowest point. The weighted lever extends over theinner edge of the sound box 7 and the screw 24 is so adjusted thatwhenthe sound box is in the horizontal position shown lin Fig. 2, theweight is supported wholly by the bracket 17` and is entirely clear andindependent of the sound box or speaker-,but when the sound box 7 istilted to the oblique position shown in Fig. 3, the inner edge of thesound box strikes and lifts slightly the weight so that. the latterrests upon or is sustained by thelsound box.

The operation is as follows: When the instrument is used as a recorder,the lever 15 is raised to the vertical position, as shown in Fig. 2, andthe sound box allowed to assumel its horizontal position, thus bringing"the recording stylus 12 into active position and relieving theinstrument of the weight v22. The record is then made in the usual wayby transmitting the voice or other sounds through the tube to the top ofthe diaphragm. lVhen the record has thus been made, if and when it isdesired to re r0- duce, the lever 15 is thrown downwar to the positionshown in Fig. 3 which'renioves the recording stylus 12 andsimultaneously throws into active position the reproducing stylus 13..At the saine time the forward upper edge of frame 7 strikes and liftsthe lever 22- thus transferring its weight from the bracket 17 or otherpartnofmthe frame to which it may be attached, to the sound box frame.This weight which is thus added to the instrument is of the Jroperamount to parts, but that it merely requires the operator 'to shift theposition of lever 15. The cost of this combined device is only a triflemore. than that o t either the recorder or repl'oducer alone and noskill is required to make the change from one to the other.

' The construction of Fig. ft is the equivalent in every sense of thatof F igs. 1 to 3. since v a spring is used instead of its equivalent,the weight. ln tl'iis'vconstruction' the weight becomes a. mere lever25, having the saine stop screw- 24, but provided with a tension spring2G which/tends to throw the lever "25 downward with a force dependentupon the noaa-:tio

fot', the sound box; it is pivoted to the carriage at 28 and rests upona lug 29. carried by a pivoted lever 30, which lever is to bemanipulated by hand. The stylus points radiate from a hub 30 which ispivoted to brackets 3l attached. to the diaphragm. The hub is fixed upona'roclr-shaft 32 which also carries a fork 33 between the legs of whichis a pin 34; carried by lever 30. lVhen lever 30 is swung to one side'or the.other, the styluses are shifted and the weight 35 is raised orlowered by the lug 29, thus either lifting the weight from or addigjitto the instrument.

The essential eaturel of my invention 'therefore is any structurecomprising the elements common to a recorder and a reproducer incombination with a weight or its equivalent adapted to be added `theretoor removedtherefrom according to the requirements ofthe operation.
